Trick is, that’s a pair of cards that have to go into “CD interconnect slots” (mentioned in the video).
At the time, the 22-bit single card RLV12 controller was well over $800, so we both had the older 18-bit 2-card RLV11 controller. He had an RL02 drive (10MB) on his, and I had an RL01 drive (5MB) on mine. For one job, I did my work on my own PDP-11/23 and would deliver it to my boss who had an H-11 of his own for his work. I worked on various DEC PDP-11 systems in the 80s. That’s the excitement for the H-11 when introduced in a multipage spread with the H8. (Yes, the TI 99/4, but I don’t think anyone used it for serious use. Useful at the time for a few, but never making big inroads. The earky 16 bit turned out to be also-rans. They didn’t know what was coming.īy the time Cromemco and Godbout (and the Seattle Computer Products 8086 S-100 board) came after, things were already shaking out. People bought into what was available, if they had the money and need. A few years is nothing when you look back, but it’s a long time when looking forward. These were before, or concurrent with the Heath H-8.

The Intersil 6100, CMOS that also happened to run PDP-8 code (well that was a 12 bit). The Alpha Microsystems using the Western Digital WD16. I know about the TI single board 9900 computer. Sometime that year Byte had an article about the LSI-11. Not the dawn of home computers, but before most people knew about them.īyte for Feb 1976, six issues in, a small bit that SCCS had already gotten fifty buyers into a group buy for the LSI-11. It was obsolete before it hit the shelves, but that didn’t matter much at the time since there were so many people who had learned on college PDP-8 and PDP-11 and VAX.Īnd I’m talking September 1975, first issue of Byte. Heathkit had very cool stuff and I can recall the surprised and excited people when this H-11 was announced. However, I DID personally have the heath terminal that looks like the H8 computer without the floppy. And you got some OK graphics and lots of expansion as well.) (You could get all that in an Apple II with a 7″ or 9″ monochrome (non-Apple) monitor for the price of a DEC VT100 terminal. The Apples ran DOS3.3 and BASIC and a good assembler, Orca/C, Kyan Pascal and Kyan’s Unixy OS KIX, and a Forth that did not need an OS and had a nice assembler built in. We had some Apple IIs with floppy’s and they ran circles around the LSI-11 setups. Trouble shooting therefore took a very long time. I don’t recall what the OS was but I’m thinking RT11? Anyway, it took about 2 hours to boot from those tapes. I had to make enclosure for six DEC LSI-11 boards and their little tape drive back in the early 1980’s. Posted in Retrocomputing Tagged DEC PDP-11, heathkit, pdp-11, retrocomputing Post navigation If you want to see what assembly language looked like on this machine, there’s a tutorial. There are plenty of ways to emulate a PDP-11 on things like Arduinos.
Replacing it put the power supply right and now he’s ready to see if the thing will start up. A diode wasn’t attached properly but it wasn’t clear if it had been damaged in transit or if it had never been installed correctly. The power supply needed some care, as you might expect. However, Heathkit had its own boards that you did build along with things like power supplies. Even though the computer is a Heathkit, the CPU board came from DEC assembled. We miss the days that your computer broke down into multiple boards plugged into a backplane. We are looking forward to seeing more videos on this computer. It is amazing when you think of today’s laptop motherboards that pack way more into a much smaller space. takes us through a tour of all the different cards inside the thing.

Unlike a lot of computers of its day, the H11 didn’t have a lot of switches and lights, but it did have an amazing software library for its day. Like a proper LSI-11, the computer uses the DEC QBus. Well, technically, it is an LSI-11 but still. He recently picked up a Heathkit H11A which, as you might remember, is actually a PDP-11 from DEC.
